Abstract: Double shearing rams designed for use in a standard ram-type blowout preventer used in oil and gas drilling and workover operations are disclosed. The double shearing rams include an upper shear ram and a mating lower shear ram. The upper shear ram includes an upper cutting blade and a lower guide blade vertically spaced to form a cavity therebetween. The cavity is sized to receive the lower ram's cutting blade in close fitting engagement when the rams are closed. The upper shear ram has a primary cutting edge formed on its leading edge and a secondary edge vertically and axially displaced from the primary cutting edge. During shearing operations, initial movement of the shear rams allows the upper shear ram's primary cutting edge to cooperate with the lower shear ram's cutting blade to make an initial shear of the member or members in the blowout preventer's bore. Further closing of the shear rams allows the upper shear ram's secondary cutting edge to cooperate with the lower shear ram's cutting blade to make a second shear of any remaining member or members in the blowout preventers bore. A plurality of guide pins positioned on the upper shear ram and the lower shear ram notched cutting edge cooperate to maintain the members to be sheared between the upper and lower shear ram.

Filed: 1999-08-26
Abstract: L'invention concerne un dispositif (10) de détection optique permettant de détecter la présence ou la concentration d'un analyte au moyen de canaux indicateurs et de canaux de référence. Ledit dispositif de détection est constitué d'un corps (12) renfermant une source (18) de rayonnements. Les rayonnements émis par cette source interagissent avec les molécules (16) indicatrices sur membrane (3) indicatrice à proximité de la surface du corps. Une caractéristique optique au moins de ces molécules indicatrices varie en fonction de la concentration de l'analyte. Par exemple, le niveau de fluorescence des molécules indicatrices fluorescentes ou la quantité de lumière absorbée par les molécules indicatrices photo-absorbantes peut varier en fonction de la concentration de l'analyte. En outre, les rayonnements émis par la source interagissent avec les molécules indicatrices situées sur la membrane de référence à proximité de la surface du corps. Les rayonnements (notamment, la lumière) émis ou réfléchis par ces molécules indicatrices pénètrent dans le corps du détecteur, où ils sont réfléchis intérieurement. Des éléments photosensibles situés à l'intérieur du corps du détecteur génèrent des signaux de canal indicateur et des signaux de canal de référence afin de donner une indication précise de la concentration de l'analyte. Selon ses modes de réalisation préférés, le dispositif de détection de l'invention est totalement autonome, et de par sa taille et sa forme, il est destiné à être utilisé in vivo dans le corps d'un être humain. Dans de tels modes de réalisation, il comprend, de préférence, une source d'alimentation, telle qu'un inducteur, qui alimente la source de rayonnements au moyen de dispositifs externes, ainsi qu'un émetteur, notamment un inducteur, servant à transmettre à des capteurs externes le signal représentant la concentration de l'analyte.

Patent CA-2347820-A1 (CA)
Title: Flap mechanism
Inventor: MAIER STEFAN
IPC: F02D9/10
Filed: 1999-10-14
Abstract: The invention relates to a flap mechanism which comprises means for compensating tolerances and the shrinkage behavior of the flap (11). These means exist primarily by the provision of a flap edge (14) which is connected by injection molding after the injection molded flap (11) has cooled, and thus reduces the gap between the flap (11) and the flap frame (10), said gap being produced by the shrinkage of the flap. In addition, the mounting of the shaft (12) in the frame (10) can be realized in an at least partially conical manner, whereby the shrinkage behavior of the flap shaft can be used, especially in an axial direction, in order to produce a mounting which is free of play. As a result, it is no longer necessary to use additional sealing elements on the mounting points of the flap. In addition, the flap is prevented from vibrating in the mounting which, in the worst case scenario, could lead to a destruction of the flap.
